The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"toi-2260-b","name":"TOI-2260 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":330.2365940019799,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":247.6669998,"dec_deg":49.0467891,"epoch_ra_deg":247.852907,"epoch_dec_deg":48.988033,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2260","semi_major_axis_km":1451099.34579,"periapsis_km":null,"mass_kg":1.9469267248999894e+25,"mass_msun":0.00000979138,"constellation":"Hercules","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-2260-b","radius_km":10332.522,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2260","host_v_mag":10.474,"uncertainties":{"radius_km":[829.153,829.153],"distance_ly":[0.9230225489383838,0.9262841127155512],"host_mass_solar":[0.04,0.04],"host_radius_solar":[0.05,0.05],"host_temperature_k":[100,100],"semi_major_axis_km":[14959.78707,14959.78707],"orbital_period_days":[0.0000047,0.0000047]},"host_mass_solar":0.99,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.94,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"G V","host_temperature_k":5534,"orbital_period_days":0.3524728,"transit_midpoint_bjd":2458928.239,"equilibrium_temperature_k":2609},"designations":[{"catalog":"Exoplanet","designation":"TOI-2260 b"},{"catalog":"Host star","designation":"TOI-2260"}],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
